What solution do the doom-troopers propose to the problem of public resistance? Let’s suspend democracy, like we did in the good old days! While one leading liberal writer insists that all the main parties must include identical austerity measures in their manifestos (not much change there then), another feminist veteran, Rosie Boycott, demands that they dump party politics altogether and form a national coalition based on Churchill’s wartime Government.
